w. s. MEGGITT SEALING MEANS FOR LIQUID CONTAINERS Filed May 29, 1928 .S.Meggitt Patented Oct. 1, 1929 WILLIAM S. MEGGITT, OF OMAHA, NEBRASKA SEALING MEANS FOR LIQUID CONTAINERS Application filed May 29,

The present invention relates to improvements in sealing means for liquid containers, and is particularly adapted for use in connection with such liquids as paint, which deteriorates upon contact with the atmosphere.

An object of the invention is to provide a combined closure and pouring means for the container in which an effective seal is provided against the admission of air and foreign matter when the device is in the closed position.

Another object of the invention resides in providing a simply constructed and compact container closure wherein the parts are secured in sealed and closed position, but are constructed for quick release and opening.

It is a further object of the invention to. provide an improved container closure and pouring spout arrangement in which the container may be closed by rotating the spout member to one angular positionand opened by the simple rotation of the spout member to a different angular position, and wherein the parts are placed under tension and held against rotary movement when in the closed position to effect a tight'sealing of the container.

With the foregoing and other objects in view, the invention will be more fully dehereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views, I

Figure 1 is a vertical section, with parts shown in elevation, of an improved device constructed in accordance with the present invention and shown in full lines in the closed and in dotted lines in the open position, and

Figure 2 is a top plan view showing the parts in the open position. I

Referring more particularly to the drawings 3 designates a can or container body of sheet metal or other material and 4 represents the upstanding threaded neck through which the liquid contents is received and removed.

In accordance with the present invention a threaded flange 5 is shown as engaged with scribed hereinafter, and will. be more particularly pointed out in'the claims appended 1928'. Serial 110,281,496.

the threaded neck 4, the engagement being preferably an air tight one. The flange 5 depends from the lower horizontal wall 6 on the rim portion of the cover 7. The upper Wall 8 of the rim portion is spaced above the wall 6 and connected therewith only at the outer edges of the walls by a rounded or the base of the spout 25, carried by the cap 10, to move into and out of registry with the 7 orifice or vent 12 made in the convex cover 7 offset from the-axis of rotation. The cover 10 is provided with the rim wall 13 which lies in a substantially horizontal plane and upon the upper rim wall 8 of the cover 7 This wall 13 connects by a rounded connecting rim piece 1 1 with the lower wall or flange 15 having the inwardly and downwardly curved edge 16.

The lower wall 15 engages with the lower wall 6. The lip portion 16 enables the trough or flange made up of the parts'13, 14 and 15 to be sprung over the rimportions 6, 8, 9 of the cover; and the parts thus become interlocked together although permitting of a 5 rotary movement of the cap upon the cover.

The side walls 17 of the trough are preferably formed with the notches 18 near the outer ends of the side walls which outer ends 19 are curved or in the form of cam surfaces. A handle" member on the container is provided with a connecting bar 20 for riding up the cam edges 19 and settling in the notches 18. This bar is carried by the side arms 21 and 22 which in turn are secured to the hinge bar 23 held in the casing 24, which is affixed to the upper portion of the container 3 in any suitable manner and in position to engage the spout 25 when the same is in the closed position shown in Figure 1. I

In the operation of the device, the parts are shown in Figure 1 in the closed and locked position, While in Figure 2, they are shown in the open pouring position.

In Figure 2 the openings 11 and 12 are in registry so that on tilting of the container, and the handle 20 is useful for this purpose, the liquid contents of th-econtainer willissue through the openings 11 and 12 and onto the.

trough-like spout 25. \Vhen the container is again set upright and t is desirable to close the same, the cap 10 lSIOHliJGd to shift the p V spout from the dotted line position in I igure 1 to the full line position, and thereupon the rectangular open handie member is swung up :fromthe position shown in Figure 2 to that shown in Figure 1.

In so doing thebar 29 will engage the cam edges .19/and will act to depress the spout member 25. 'Ihe spout member andthe cap 7 arelthus placed LlIlClfil lGIlSlOl'l. This tension is useful foricausing the notched portion c I 18 of the spout member to snap against the locking ,barQO, but even in this position the tension willnot be entirely relieved but a certain tension; will stillbecommunicated to i, the members 7 ELDClwlO, whereby the blank portion of the cap 10 will, fit tightly about the vent 11' andrcause an :efiective sealing of the container both against theadmission of air and foreign substances which would tend to contaminate and cause deterioration of the contents of the vessel.

The containermay be quickly opened by slightly depressing the outerend of the spout member 25-and in forcing the locking bar 20,0ff the end of thexspout; or by simply i performing the latter act which will cause the bar 20 to ride up the curved edges of the notches 18 and depress the spout=sufficiently to permitescape of the'bar. 1 hen the spout is free of the container, it may be rotated with the cap 7 to the dotted line position shown in Figure l. The expansion of the resilient,

walls 6 and 8 'upon the resilient walls 13 and 15 will prevent entrance of air about the rim and flange portion.

. I do not wish to be restricted to-the size,

form and proportions 'ofthe various parts,

' let orifice, a spout 'rotatable with respect to the cover for moving into and out of-registry with said orifice for opening and closing the container, and means for engaging said spout and placing the same under tension when in the closed position to seal the con tainer.

3. In a container, a yieldable cover having an outlet vent, a yieldable and rotatable cap on the cover for closing said orifice and having a spout opening through the cap to the orifice in one angular position of the cap, and means" for engaging said spout for holding the cap against angular movement and for also flexing the cap down upon the cover for sealing the 'o "ifice.

4. In a container a convex resilient cover 2 l12LV1Il a vent therein a concave resilient ca 3 rotatably rfitted on the cover for closing the vent, a spout on said cap opening through the cap and adapted to register with the vent 111 one angular position of the cap, and means engaging the spout for holding the cap against rotation andfor placing a tension upon the resilient cap and cover to seal the vent. I

5. In a container, a fixed upwardly convex resilient cover having a vent offset from its center, a resilient concave cap interlocked with said cover but adapted to rotate relatively thereto, a spout on the cap offset from the center of rotation and opening through the lower face of the cap for placing the spout in communication with the vent in one angular position of the cap, and means on the container for moving into'and out of engagement with the spout when the vent is closed by said cap for holding the spout and cap against rotary movement.

6. In a container, a perforated cover, a rotatable cover thereon having a spout at one side for alining with the perforated portion of the cover, and a swinging member adapted toengage the spout invone angular position thereof for holding the spout against rotary movement.

7; In a container, a perforated cover, a

cap rotatable with respect to the cover and having a spout adapted to register with the perforated portion of the cover and having a notched portion, and a swinging handle for engaging in the notched portion of the spout against'rotation.

8. In a container, a perforated cover, a cap rotatable with respect tothe cover and having aspout'for moving into and out of alinement with the perforated portion of the cover, said spout having a trough and side walls with notched upper portions and rounded outer end portions, and a substantially rectangular handle hinged on thecontainer and adapted to swing about said spout for engaging the rounded end portions and to interlock in said notches, said handle adapted .to-draw the spout resiliently toward the container for placing the cap and cover under tension.

9. In a container, a container body having a threaded upstanding neck, a perforated cover having a overhanging rim composed of spaced double walls and provided with a downwardly extending threaded flange for engaging the threaded neck, a cap having a flange-d portion enveloping the rim of the cover, a spout carried at one side of the cap, and a bail for slipping over the end of said spout in one position thereof.

In testimony whereof, I have affixed my signature.
